SPECIFICATION forming part of Letters Patent N 0. 480,035, dated August2, 1892.

Application filed January 4,18921 Serial No. 416,974. (No model.)

To all whom it may concern:

Be it known that I, DANIEL REED, of Ansonia,in the county of New Havenand State of Connecticut, have invented a new Improvement inCutlery-Grinders; andI do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1, a view of the device in side elevation; Fig. 2, a plan viewthereof; Fig.3, a broken View showing an upright of one of therest-carriers in elevation, while the rest applied to it is representedin vertical section Fig. 4, a broken view, in side elevation, showing amodified form of rest.

My invention relates to an improvement in machines for grinding cutlery,the object be ing to produce for this purpose a simple, convenient, andeffective device.

WVith these ends in view my invention consists in a machine havingcertain details of construction and combinations of parts, as will behereinafter described, an dpointed out in the claims.

As herein shown, the grindstone A, which may be of any approvedconstruction, is journaled in bearings B B, secured to opposite edges ofa low standard C;which is furnished with a trough D, located below thesaid stone. A bevel-gear E, mounted on the shaft carrying the stone,meshes into a corresponding gear F, secured to the inner end of adrivingshaft G, the opposite end whereof is furnished with a handle H,the said shaft being journaled in the arms I I of a frame I, which issecured bybolts I I to one edge of the standard C.

As shown by Figs. 1 and 2 of the drawings, the device is provided withtwo laterally-adjustable rest-carriers, respectively located at oppositeends of the standard and in line with the grindstone. Each of the saidcarriers comprises an upright J, having one of its faces provided with avertical series of transverse pockets J and two horizontallongitudinallyslotted feet J J sufficiently separated to straddle thetrough D and rest upon the opposite sides of the standard, their slots JJ receiving bolts K K, by means of which they are adjustably securedthereto. As shown in the said figures of the drawings, one of the saidrest-carriers is provided with a rest L, having a vertical centralopening L, adapting it to fit over the upright of the rest-carrier towhich it is applied and upon which it is vertically adjusted and securedin any desired position by means of a set-screw L which draws atransverse rib L (see Fig. 3,) projecting into its opening L into one ofthe grooves J on the face of the upright. The

inner end of this rest is furnished with a straight or squareoperating-face L, which stands in a vertical plane and has its extremelower end provided with an inwardly-projecting curved lip Z. This restis designed for sharpening knives, which are better held up to the stoneby means of the said curved lip, which throws their edges inward ontothe stone and constantly urges them in that direction, while the upperedges or backs of the knives rest upon the straight portion of the saidoperating-face, which, therefore, when made as described, holds theknives steady and enables their edges to be nicely and accuratelyground, whereas rests having concaved faces as heretofore made favor awabbling motion of the knives and prevent them from being so nicelysharpened. Theupright of the other rest-carrier is furnished with a restM, having a central opening h and furnished with a set-screw M andconstructed with an inclined operating-face M which will be found veryconvenient for supporting the blades of shears and scissors in rightrelation to the stone. If preferred, this face may be very slightlyconcaved to suit the ordinary conformation of shears and scissor-blades.

This rest is also adapted to be secured in any position of adjustment bymeans of an inwardly-proj ectin g trans verse rib, (not shown,) butcorresponding to the rib L (illustrated by Fig. 3 of the drawings.) I donot necessarily employ two restcarriers, however, as one will answer thepurpose, and instead of employing two independent rests I may combinethem in one, as shown by Fig. 4 of the drawings, in which the rest N isprovided at one end with a square operating-face N, corresponding to theface L before described, and

at its opposite end with an inclined operating-face N corresponding tothe face M before described.

It will be understood that the rest or rests are raised or loweredaccording to the degree of bevel to he imparted to the edge beingsharpened.

A cutlery-grinder thus constructed will he found very convenient tooperate and very ettective in use on account of the ease of adjustingthe rests and of the superior way in which they present the objects tobe ground to the stone.

Having fully described my invention, what I claim as new, an d desire tosecure by Letters Patent, is-

1. In a machine for grinding cutlery, the combination, with the standardthereof, of a grindstone journaled thereupon, means for rotating thesaid stone, a laterally-adjustable restcarrier having two correspondinghorizontal slotted feet adapted in their spread to rest upon theopposite sides of the said standard at one end thereof, and an uprightrising centrally between the said feet, and a rest having an opening toadapt it to fit over the said upright to which it is ad justablysecured.

2. In a machine for grinding cutlery, a rest having a square faceconstructed at its lower edge with an inwardly-projecting curved lip,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

DANIEL REED.
